WinUAE v5.1.0 Beta 12 is released. WinUAE is the commodore amiga emulator for Windows. WinUAE is a mostly complete software emulation of the hardware of the Commodore Amiga 500/1000/2000. A Commodore Amiga, for those who don’t know, is a 16/32 bit computer system based on the Motorola 680×0 CPU and a few specially designed custom chips that provide very good graphics and sound capabilities. Its first incarnation, the A1000, appeared in 1985, followed by the highly successful A500 and A2000 models. WinUAE is a port of the originally written for Unixish systems UAE; but over time, it seems the Windows port, WinUAE has become the best version available on any platform. WinUAE is free software: you are welcome to distribute copies of it and/or modify it, under certain conditions. There is no warranty of any kind for UAE. For more details concerning these issues, please read the GNU General Public License, which describes the terms under which WinUAE is distributed.

WinUAE v5.1.0 Beta 12 Changelog:
- b9 "'Restart' GUI button didn't reset current windowed/fullscreen mode flag" was wrong. Fixed correctly now.
- Some ECS Denise ECS-only features (mainly borderblank) didn't work (b1)
- Full-window mode in another monitor with different DPI than monitor where GUI position was previously stored and GUI is opened: GUI used wrong DPI value.
- CSMK3/PPC boot ROM seems to do hidden adjustments at least to DBLxxx WB screen modes (for example slightly more lines and refresh rate from 48Hz to 50Hz) and these modes with max overscan had few pixels cut from left border. This fixes it but if it also affects badly some other modes, I'll revert this change because "Overscan+" also fixed it. Please check if you use programmed modes in WB. (I didn't notice any but there are too many different variants to test and they can change between OS versions or have manual adjustments added) EDIT: Apparently CSMK3 does same as VGAOnly "monitor driver".
- Backslash/F11 option incorrectly affected on screen keyboard keys.
- Added debugger calculator rl()/rw()/rb() functions that read value from address, for example "m rl(rl(4)+10)" returns address to exec base name. Improved support for hexadecimal numbers in calculator formulas.
- Debugger 'v' and 'V' remembers previous vertical and horizontal value.
